Description

Technical Field

[0001] This application relates to the field of alarm technology, and in particular to an anti-pull-out alarm device. Background Technology

[0002] In industrial operations, the connection of mobile devices, such as tank trucks or tank cars, with supporting equipment is widespread. In existing technologies, the connection must be disconnected in a specific sequence after the operation to ensure safety. That is, the connection between the tank truck and the supporting equipment must be actively disconnected before the mobile device is removed. However, in actual operation, human negligence often leads to misoperation, and the mobile device is moved without disconnecting the connection according to the prescribed procedure, resulting in passive breakage or even structural damage at the connection point of the device. Such errors may cause serious safety accidents such as media leakage, equipment damage, or electric shock. In existing technologies, breakaway valves are usually used to prevent leakage accidents caused by accidental pipeline breakage. However, in practical applications, breakaway valves are often disposable consumables and are expensive. Although there are reusable emergency breakaway valves on the market, there is also a risk of contamination during reuse. When using breakaway valves, the cost is high, and there is a risk of contamination when reused. Moreover, the focus is on post-event solutions rather than pre-event prevention.

[0003] Therefore, an anti-pull-out alarm device is proposed to address the aforementioned technical issues. Summary of the Invention

[0004] To address the aforementioned issues, this application provides an anti-pull-out alarm device.

[0005] This application provides an anti-pull-out alarm device, which adopts the following technical solution: An anti-pull-out alarm device includes a trigger connection part and a pipe connection part. The trigger connection part is fixedly embedded in the tanker seat, and an alarm light is fixedly installed on the trigger connection part. The pipe connection part includes a first connector and a second connector. The first connector is fixedly connected to the tanker, and the second connector is fixedly connected to a connecting pipe. The first connector is fixedly connected to the second connector via a magnetic connection assembly. An annular sleeve is fixedly sleeved on one end of the first connector. A positive conductive ring is slidably engaged between the annular sleeve and the first connector, and the positive conductive ring is secured by a first return spring. The annular sleeve is elastically connected to the inner wall of one end. The lateral limiting component is fixedly installed on the outer wall of the annular sleeve. The negative conductive ring is installed on the lateral limiting component. The negative conductive ring is located on one side of the positive conductive ring. The negative conductive ring corresponds to the push protrusion fixed on the outer wall of the second connector. Both the positive and negative conductive rings are electrically connected to the trigger connection part. The rotating sealing plate is installed on the inner wall of the first connector. The rotating sealing plate is rotatably connected to the first connector through the rotating connecting shaft. One end of the rotating connecting shaft is connected to the lateral limiting component through the linkage component.

[0006] By adopting the above technical solution, when the first connector and the second connector are connected, the circuit of the alarm light is closed. When the driver gets into the vehicle and sits in the seat, the alarm light will sound an alarm to remind the driver that the pipeline and the tanker are not disconnected. At the same time, when the circuit of the alarm light is open, the pipeline and the tanker are disconnected. At this time, the driver can drive the tanker normally, effectively avoiding the occurrence of a breakage accident.

[0007] Preferably, the trigger connection includes the support plate and the buffer lifting plate, the buffer lifting plate and the support plate are elastically connected by the damping spring, and both the buffer lifting plate and the support plate are embedded in the tanker seat. The buffer lifting plate is embedded with the first conductive wire and the second conductive wire, and the positive and negative poles of the alarm light are connected to the positive conductive ring and the negative conductive ring respectively through the first conductive wire and the second conductive wire.

[0008] By adopting the above technical solution, controlling the positive conductive ring and the negative conductive ring to be connected in close contact, the circuit of the alarm light can be made open under the action of the first conductive line and the second conductive line.

[0009] Preferably, the control pressure head is fixedly installed at the bottom of the buffer lifting plate, and the touch switch is fixedly installed at the top of the support plate. The touch switch is vertically corresponding to the control pressure head, and the touch switch is used to control the alarm light.

[0010] By adopting the above technical solution, when the buffer lifting plate descends, it can drive the control pressure head to contact the touch switch, and realize the opening and closing control of the alarm light through the touch switch.

[0011] Preferably, the magnetic connection assembly includes a connecting magnetic ring and an electromagnetic ring. The connecting magnetic ring is fixed to one end of the second connector, and the electromagnetic ring is fixed to the inner wall of the connecting slot opened at one end of the first connector, with one end of the second connector inserted into the connecting slot.

[0012] By adopting the above technical solution, the second connector is inserted into the connection slot, so that the connecting magnetic ring and the electromagnetic ring are in close contact. The electromagnetic ring is energized, so that the connecting magnetic ring and the electromagnetic ring are fixedly attracted, thereby achieving a fixed connection between the second connector and the first connector, thus connecting the pipeline to the tanker.

[0013] Preferably, the lateral limiting component includes the positioning mounting base and the movable push block. The positioning mounting base is fixed on the outer wall of one end of the annular sleeve. The lateral limiting slide rod is fixedly installed on the side wall of the positioning mounting base. The movable push block is slidably sleeved on the lateral limiting slide rod, and the movable push block corresponds to the clearance groove opened on the annular sleeve. The negative conductive ring is fixedly connected to the movable push block.

[0014] By adopting the above technical solution, when the pushing protrusion pushes the negative conductive ring to move, the negative conductive ring can slide on the transverse limiting slide bar through the moving push block.

[0015] Preferably, the movable push block is elastically connected to the positioning mounting base via the second return spring, and the second return spring is sleeved on the lateral limiting slide bar.

[0016] By adopting the above technical solution, under the action of the second reset spring, the moving push block can drive the negative conductive ring to reset.

[0017] Preferably, a circular stop block is fixedly installed at one end of the lateral limiting slide bar, and the circular stop block is used to limit the movement of the push block.

[0018] By adopting the above technical solution, the moving push block can be prevented from slipping under the action of the circular grid block.

[0019] Preferably, the linkage assembly includes the rotary connector, the transverse rack, and the connecting gear. The rotary connector is fixedly connected to one end of the rotary connecting shaft. The transverse rack is fixed to the top of the movable push block. The connecting gear is rotatably mounted on the top of the positioning mounting base via the linkage column, and the transverse rack meshes with the connecting gear.

[0020] By adopting the above technical solution, when the movable push block moves, it can drive the transverse rack to move, thereby causing the connecting gear and the linkage column to rotate.

[0021] Preferably, the first synchronous wheel is fixedly sleeved on the linkage column, and the second synchronous wheel is fixedly sleeved on the rotary connector.

[0022] By adopting the above technical solution, the first synchronous wheel can rotate with the linkage column, and the second synchronous wheel can rotate synchronously with the rotating connector.

[0023] Preferably, the first synchronous pulley and the second synchronous pulley are connected by the synchronous belt.

[0024] By adopting the above technical solution, the first synchronous pulley and the second synchronous pulley can rotate synchronously under the action of the synchronous belt.

[0025] Compared with existing technologies, this anti-pull-out alarm device triggers the connection by using the sinking of the buffer lifting plate when the driver sits down, causing the control head to press down the touch switch. Combined with the circuit on / off status, it controls the alarm light to remind the driver of the pipeline connection status, facilitating timely handling and effectively preventing tank trucks from driving in the pipeline connection state, reducing safety hazards and improving transportation safety.

[0026] Compared with existing technologies, this anti-pull-out alarm device uses a magnetic connection component to firmly connect the first connector and the second connector, ensuring connection reliability while making connection more convenient. At the same time, the lateral limiting component and the linkage component work together to achieve contact and conduction of the positive and negative conductive rings while precisely controlling the opening or closing of the first connector by rotating the sealing plate, which does not affect use and avoids leakage.

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail below.

[0031] A pull-out alarm device, referring to Figure 1 , Figure 2 and Figure 3The system includes a trigger connection part 1 and a pipe connection part 2. The trigger connection part 1 is fixedly embedded in the tanker seat and an alarm light 3 is fixedly installed on it. The pipe connection part 2 includes a first connector 4 and a second connector 5. The first connector 4 is fixedly connected to the tanker, and the second connector 5 is fixedly connected to the connecting pipe. The first connector 4 is fixedly connected to the second connector 5 through a magnetic connection assembly 6. When the tanker is connected to the connecting pipe, the second connector 5 is inserted into the first connector 4, and the magnetic connection assembly 6 is attracted and fixed. An annular sleeve 7 is fixedly sleeved on one end of the first connector 4. A positive conductive ring 8 is slidably engaged between the annular sleeve 7 and the first connector 4, and the positive conductive ring 8 is elastically connected to the inner wall of one end of the annular sleeve 7 through a first return spring 9. A lateral limiting assembly 10 is fixedly installed on the outer wall of the annular sleeve 7 for lateral limiting. A negative conductive ring 11 is installed on component 10. The negative conductive ring 11 is located on the side of the positive conductive ring 8. The negative conductive ring 11 corresponds to the push protrusion 12 fixed on the outer wall of the second connector 5. Both the positive conductive ring 8 and the negative conductive ring 11 are electrically connected to the trigger connection part 1. When the first connector 4 and the second connector 5 are not connected, the push protrusion 12 of the second connector 5 does not push the negative conductive ring 11, the positive conductive ring 8 and the negative conductive ring 11 do not contact each other, the alarm light 3 circuit is disconnected, the trigger connection part 1 cannot control the alarm light 3, and the driver can drive normally. When the first connector 4 and the second connector 5 are connected, the positive conductive ring 8 and the negative conductive ring 11 contact each other. When the driver gets into the car and sits in the seat, the trigger connection part 1 controls the alarm light 3 to turn on, reminding the driver that the pipeline is not disconnected, so that the driver can take the correct action in time. A rotating sealing plate 13 is installed on the inner wall of the first connector 4. The rotating sealing plate 13 is rotatably connected to the first connector 4 via a rotating connecting shaft 14, and one end of the rotating connecting shaft 14 is connected to the lateral limiting component 10 via a linkage component 15. During the connection process between the second connector 5 and the first connector 4, the lateral limiting component 10 drives the rotating connecting shaft 14 to rotate via the linkage component 15, so that the rotating sealing plate 13 blocks or opens the first connector 4. When the first connector 4 and the second connector 5 are not connected, the rotating sealing plate 13 closes the first connector 4. When the first connector 4 and the second connector 5 are connected, the rotating sealing plate 13 rotates to open the first connector 4. This allows the first connector 4 to be opened and closed in a timely manner during use, avoiding leakage risks without affecting its use.

[0032] Reference Figure 1The trigger connection part 1 includes a support plate 101 and a buffer lifting plate 102. The buffer lifting plate 102 and the support plate 101 are elastically connected by a damping spring 103. Both the buffer lifting plate 102 and the support plate 101 are embedded in the tanker seat. A first conductive wire 104 and a second conductive wire 105 are embedded in the buffer lifting plate 102. The positive and negative poles of the alarm light 3 are connected to the positive conductive ring 8 and the negative conductive ring 11 respectively through the first conductive wire 104 and the second conductive wire 105. A control pressure head 106 is fixedly installed at the bottom of the buffer lifting plate 102, and a touch switch 107 is fixedly installed at the top of the support plate 101. The touch switch 107 is vertically corresponding to the control pressure head 106 and is used to control the alarm light 3. When the tanker is not connected to the connecting pipe, the first connector 4 and the second connector 5 are not connected, the positive and negative conductive rings 11 are not in contact, and the circuit is broken. When the driver sits in the seat, the buffer lifting plate 102 is pressed down along the damping spring 103. Although the control pressure head 106 touches the touch switch 107 on the support plate 101, the alarm light 3 does not sound. When connecting the pipeline, the positive conductive ring 8 and the negative conductive ring 11 contact to make the circuit conductive. At this time, when the driver sits down, the buffer lifting plate 102 sinks, and the control pressure head 106 presses down the touch switch 107, triggering the connection part 1 to control the alarm light 3 to turn on, reminding the driver that the pipeline has been connected and needs to be handled promptly and correctly.

[0033] Reference Figure 3 The magnetic connection assembly 6 includes a connecting magnetic ring 601 and an electromagnetic ring 602. The connecting magnetic ring 601 is fixed to one end of the second connector 5, and the electromagnetic ring 602 is fixed to the inner wall of the connection slot at one end of the first connector 4, with one end of the second connector 5 inserted into the connection slot. When connecting the pipe, one end of the second connector 5 is inserted into the connection slot of the first connector 4. At this time, the connecting magnetic ring 601 on the second connector 5 approaches the electromagnetic ring 602 on the inner wall of the connection slot. The electromagnetic ring 602 is energized to generate magnetic force, attracting the connecting magnetic ring 601, thereby firmly connecting the first connector 4 and the second connector 5 together.

[0034] Reference Figure 5The lateral limiting component 10 includes a positioning mounting base 1001 and a movable push block 1002. The positioning mounting base 1001 is fixed on the outer wall of one end of the annular sleeve 7. A lateral limiting slide rod 1003 is fixedly installed on the side wall of the positioning mounting base 1001. The movable push block 1002 is slidably sleeved on the lateral limiting slide rod 1003, and the movable push block 1002 corresponds to the clearance groove opened on the annular sleeve 7. The negative conductive ring 11 is fixedly connected to the movable push block 1002. The movable push block 1002 is elastically connected to the positioning mounting base 1001 through a second return spring 1004, and the second return spring 1004 is sleeved on the lateral limiting slide rod 1003. A circular stop block 1005 is fixedly installed at one end of the lateral limiting slide rod 1003. The circular stop block 1005 is used to limit the movable push block 1002. When the second connector 5 is inserted into the first connector 4, the pushing protrusion 12 on it enters the relief groove of the annular sleeve 7 and pushes the negative conductive ring 11, which is fixed to the movable push block 1002. The movable push block 1002 slides on the transverse limiting slide bar 1003, compressing the second return spring 1004. The negative conductive ring 11 then moves and contacts the positive conductive ring 8, and the circuit is completed. When the second connector 5 is pulled out, the second return spring 1004 returns to its original position, pushing the movable push block 1002 back along the transverse limiting slide bar 1003. The negative conductive ring 11 separates from the positive conductive ring 8, the circuit is broken, and the circular stop block 1005 prevents the movable push block 1002 from sliding out of the transverse limiting slide bar 1003. Reference Figure 6 The linkage assembly 15 includes a rotary connector 1501, a transverse rack 1502, and a connecting gear 1503. The rotary connector 1501 is fixedly connected to one end of the rotary connecting shaft 14. The transverse rack 1502 is fixed to the top of the movable push block 1002. The connecting gear 1503 is rotatably mounted on the top of the positioning mounting base 1001 via a linkage column 1504, and the transverse rack 1502 is meshed with the connecting gear 1503. A first synchronous pulley 1505 is fixedly sleeved on the linkage column 1504, and a second synchronous pulley 1506 is fixedly sleeved on the rotary connector 1501. The first synchronous pulley 1505 and the second synchronous pulley 1506 are connected by a synchronous belt 1507. When the second connector 5 is inserted into the first connector 4, the movable push block 1002 slides along the transverse limiting slide bar 1003 under the action of the pushing protrusion 12, driving the transverse rack 1502 fixed at the top to move. The transverse rack 1502 meshes with the connecting gear 1503, causing the connecting gear 1503 to rotate around the linkage column 1504, and the first synchronous pulley 1505 rotates accordingly. Through the synchronous belt 1507, the first synchronous pulley 1505 drives the second synchronous pulley 1506 to rotate, which in turn causes the rotating connecting shaft 14, which is fixed to the rotating connecting member 1501, to rotate, ultimately controlling the rotating sealing plate 13 to open the first connecting head 4; when disconnecting, the components move in opposite directions, and the rotating sealing plate 13 closes the first connecting head 4.

[0035] The working process of this application is as follows: When the tanker truck is not connected to the pipeline, all components are in the initial position, the circuit is disconnected, the alarm light 3 is not lit, and the rotating sealing plate 13 closes the first connector 4. During connection, the second connector 5 is inserted into the first connector 4, the magnetic suction component is attracted and fixed, the pushing protrusion 12 pushes the moving push block 1002, so that the positive and negative conductive rings 11 contact, and the circuit is connected. At the same time, the moving push block 1002 drives the rotating connecting shaft 14 to rotate through the linkage component 15, opening the rotating sealing plate 13. The driver sits down, the buffer lifting plate 102 sinks, the control pressure head 106 presses down the touch switch 107, triggering the connection part 1 to control the alarm light 3 to light up, reminding the driver to deal with the pipeline connection situation in time.
